Early aortic growth in acute descending aortic dissection
Abstract: OBJECTIVES
Acute aortic dissection leads to the destabilization of the aortic wall, followed by an immediate increase in aortic diameter. It remains unclear how the aortic diameter changes during the dissection’s acute and subacute phases. The aim of this study was to evaluate the change in aortic geometry within 30 days after the onset of a descending aortic dissection.
METHODS
Patients with acute type B and non-A non-B dissection who had at least 2 computed tomography angiography scans obtained within 30 days after the onset of dissection were evaluated. Exclusion criteria were a thrombosed false lumen, connective tissue disorders and endovascular or open aortic repair performed prior to the second computed tomography angiography.
RESULTS
Among 190 patients with acute aortic dissection, 42 patients met our inclusion criteria. Their aortic geometry was analysed according to the computed tomography angiography scans obtained between 0–3 (N = 35), 4–7 (N = 9) and 8–30 (N = 12) days after the dissection onset. The highest aortic diameter growth rate was observed in the first quartile of the thoracic aorta and measured 0.66 (0.06; 1.03), 0.29 (−0.01; 0.41) and 0.06 (−0.13; 0.26) mm/day at 0–3, 4–7 and 8–30 days after the dissection, respectively. Proximal entry location (P = 0.037) and entry located at the arch concavity (P = 0.008) were associated with a higher aortic diameter increase.
CONCLUSIONS
Early rapid growth occurs during the first week after the descending aortic dissection—most intensely over the first 3 days, and this is associated with the location of the dissection’s entry
